"The research division's model says your fragments should be arranged in concentric rings."
Gao Jun had a stick. Not a formation tool, a stick. Actual wood, scavenged from a dead scrub tree at the Barrens' western edge during his first supply run. He'd returned with dried fruit, salt pork, three liters of water in clay jugs, and a stick that he now used to draw diagrams in the thin layer of crystal dust that coated the workshop chamber's stone floor.
The diagram showed a series of nested circles. Each circle represented a fragment tier, the innermost circle being the cornerstone, fragment one, the eighty-percent-capacity channel that anchored Lin Feng's entire template architecture. The concentric rings radiated outward, each ring containing fragments of decreasing significance, the whole assembly structured like a target with the most important component at the center.
"Ring one: cornerstone fragment. Ring two: primary consumption fragments, the first five to seven fragments consumed after the cornerstone is established. Ring three: secondary consumption fragments. Ring four: tertiary. Each ring has a specific function in the template's energy distribution system. The cornerstone generates. Ring two amplifies. Ring three distributes. Ring four executes."
Lin Feng sat cross-legged on the diagnostic platform. The four active pillars hummed at idle, the station powered down to monitoring mode, drawing minimal energy from the hub's reserves while maintaining a passive scan of his template architecture. The amber glow was dim. The corridor lights had settled into a low-power state that made the workshop feel like it existed at the bottom of a jar of honey.
"That's not how mine are arranged," Lin Feng said.
"I know. Your diagnostic showed a non-concentric structure. The fragments are clustered rather than ringed, grouped by consumption source rather than function. The junction node fragments occupy one cluster. Your original pre-consumption fragments occupy another. The partial fragments sit between the clusters with no clear organizational affiliation." Gao Jun tapped the stick against the floor. The wood made a dry sound on stone. "The research division's model predicts concentric rings because the model was built from theoretical analysis. Nobody in three centuries has been able to observe an actual Devourer template."
"The theory is wrong."
"The theory might be wrong. Or your template might be suboptimal. That's what the forty-one percent efficiency suggests. Your fragments are arranged in a pattern that doesn't match the theoretical optimum. The question is whether the theoretical optimum is actually optimal, or whether it's three hundred years of academics building castles on foundations they never tested."
The distinction mattered. Lin Feng's routing sense examined his own template architecture, a daily exercise since the diagnostic had shown him the schematic. Twenty-two active fragments, three partials. The fragments were clustered, as Gao Jun described. Not ringed. The junction node's consumed architecture had integrated as a block, a dense grouping of infrastructure-derived fragments that sat in his channel network like a transplanted organ. Functional, connected to the surrounding tissue, but structurally distinct from the native architecture.
"Try optimization point three," Gao Jun said. He circled a spot on his dust diagram, a junction between what he labeled the "consumption cluster" and the "native cluster," where the two groupings of fragments met in Lin Feng's channel network. "The diagnostic identified a routing inefficiency at the cluster boundary. Energy crossing from the node-derived fragments to your native fragments loses approximately eight percent at the junction. The division's model says that's because the junction lacks a bridge fragment, a component that translates between the two architectural languages."
"I don't have a bridge fragment."
"You have partial fragment twenty-four. It sits at the cluster boundary. The diagnostic classified it as three-quarters capacity, enough to function but not enough to perform at full output. If you reposition it to sit directly on the junction rather than adjacent to it, the partial fragment becomes the bridge. Its reduced capacity won't translate at full efficiency, but even fifty percent translation is better than the eight-percent-loss junction you currently have."
Lin Feng closed his eyes. His routing sense turned inward, the perception that usually mapped the external world of conduits and crystal and corrupted organisms redirected to the internal landscape of his own formation architecture. The template, seen from inside, was a different kind of terrain. Not flat like the Barrens. Vertical. Layered. The fragments existed in a three-dimensional space that his routing sense rendered as nodes in a network, connected by channels that carried energy the way conduits carried formation data.
Fragment twenty-four. The partial. He found it at three-quarters capacity, positioned at the border between his native fragment cluster and the consumed junction node cluster. The fragment was doing nothing useful. Sitting at the boundary, receiving energy from both clusters but transmitting to neither effectively. A component without a clear function, integrated during the node consumption but never properly assigned a role.
Repositioning it meant moving it through his channel network. Not physically. The fragments weren't objects with mass and dimension. They were patterns. Formation-frequency configurations that occupied specific positions in his channel architecture the way data occupies specific addresses in memory. Moving a fragment meant rewriting its address. Changing the channel pathways that connected it to its neighbors. Re-routing the energy flows that passed through its position.
The diagnostic station could do this with precision, the six-pillar projection system designed to guide fragments into optimal positions with the accuracy of a machine tool. Manual repositioning, without the station, was the equivalent of performing surgery by feel. Possible. Dangerous. The margin for error was the difference between a bridge fragment that improved his efficiency and a displaced fragment that damaged the channel architecture at the cluster boundary.
"Walk me through the channel topology at the junction," Lin Feng said.
Gao Jun's analytical overlay activated. The research tools, the copied node architecture that the Iron Gate Sect had reverse-engineered from infrastructure components, scanned Lin Feng's template through the diagnostic station's passive monitoring feed. The overlay couldn't see Lin Feng's internal architecture directly. It read the station's output, interpreted the data through three centuries of theoretical models, and produced an analysis that was one step removed from direct observation.
"The junction has four channel pathways crossing it. Two carry energy from the node cluster to the native cluster. Two carry energy in the reverse direction. The pathways cross at approximately forty-degree angles. Fragment twenty-four sits two channel-widths north of the crossing point." The stick scratched in the dust. An intersection. Four lines. A dot offset from the center. "Move the fragment south by two channel-widths. Center it on the crossing. The energy from both clusters will pass through the fragment instead of around it."
Lin Feng's routing sense found the four pathways. Found the crossing point. Measured the distance between fragment twenty-four's current position and the target, two channel-widths, which in the internal geometry of his template meant a formation-frequency shift of specific magnitude. He could calculate the shift. The consumed node's data-processing architecture provided the mathematical framework.
He began the move.
The fragment resisted. Not consciously; formation fragments weren't sentient. But the channel architecture had established equilibrium around the fragment's current position. Energy flows had adapted to route around it. The surrounding fragments had adjusted their own output patterns to compensate for twenty-four's inactivity. The system had optimized itself around the inefficiency, building workarounds that treated the badly placed fragment as a fixed obstacle rather than a movable component.
Moving it meant breaking the workarounds. Every compensating adjustment that his template had made since the node consumption would need to re-adjust. The equilibrium would be disrupted. Until a new equilibrium formed around the fragment's new position, his template would operate in a destabilized state, energy flows disrupted, routing pathways broken, the entire architecture shaking like a building whose support columns had been shifted.
He pushed the fragment south. One channel-width.
His right hand cramped. The fingers curled inward, an involuntary contraction, the muscles responding to the formation-frequency disruption in his channels the way muscles respond to an electrical shock. The cramp was sharp. His thumb locked against his palm. The other fingers followed, the hand clenching into a fist that his conscious mind hadn't commanded.
"Status," Gao Jun said. The professional's voice. Monitoring.
"One channel-width. Halfway. My right hand is—" The cramp intensified. Spread. His right forearm tightened, the muscles from wrist to elbow contracting in a wave that followed the channel pathway he was disrupting. The energy flow that normally powered his right arm's formation-enhanced strength was being rerouted through the destabilized junction, and the rerouting was producing spikes, surges of uncontrolled energy that hit his motor neurons like static on a signal line.
"Hold position. Let the channels stabilize before moving further."
"The channels aren't stabilizing. The workarounds are collapsing faster than new routing can form. It's—" He searched for the right analogy. Found it in the infrastructure engineering vocabulary the consumed node had given him. "—a cascade failure. I disrupted one pathway and the compensating pathways are losing their reference point. They were routing around the fragment's old position. The fragment isn't in the old position anymore. The workarounds are searching for it, sending energy to an address that's empty."
"Pull the fragment back."
"If I pull back, the workarounds might not re-form. I've already broken the equilibrium. Restoring the original position doesn't restore the original compensation patterns. The system adapts forward, not backward."
Gao Jun's stick stopped moving. The analyst's face, lit by the workshop's dim amber glow, was performing calculations that his overlay couldn't assist with. This was beyond the research division's theoretical models. No model had accounted for a live practitioner manually repositioning fragments in an active template, because no practitioner had attempted it, because no practitioner had possessed the routing sense needed to perceive their own internal architecture with sufficient resolution.
"Then finish the move. Complete the repositioning. Get the fragment to the crossing point before the cascade failure propagates further."
Lin Feng pushed. The second channel-width was worse than the first. The fragment resisted harder. The destination was the crossing point itself, the intersection of four major energy pathways, and placing a fragment at the intersection meant the fragment would immediately be subjected to energy flows from four directions simultaneously. The partial fragment, at three-quarters capacity, would need to handle four pathways' worth of energy from the moment it reached the crossing.
He put it there anyway.
Fragment twenty-four arrived at the crossing point and the four energy pathways hit it from four directions and the three-quarters-capacity component processed the incoming energy and the processing was—
Wrong.
Not the catastrophic wrong he'd feared. No channel collapse, no fragment destabilization, no cascade failure propagating through his template. A different wrong. The fragment was at the crossing. The four pathways were routing through it. The energy was being translated between the node cluster and the native cluster. But the translation was asymmetric. The fragment handled energy flowing from the node cluster to the native cluster efficiently, the infrastructure-derived architecture on one side speaking to the fragment's partial formation data and producing clean output on the other side. Energy flowing in the reverse direction, native to node, was being garbled. The fragment couldn't translate in both directions equally. It was a one-way bridge.
"The division's model was wrong," Lin Feng said. His right hand uncramped. The spasms eased as the new routing established itself, unstable, imperfect, but functional. The four pathways were flowing. The fragment was working. Badly. "The bridge fragment theory assumes bilateral translation. Fragment twenty-four translates node-to-native but not native-to-node. The reverse flow is degraded. Worse than the original eight-percent loss."
"Worse how?"
"Twelve percent loss on the reverse flow. The original junction lost eight percent in both directions. The bridge fragment gains on node-to-native, loss drops to three percent in that direction. But native-to-node goes from eight to twelve." He ran the numbers. The consumed node's processing architecture handled the calculation. "Net efficiency change: positive one-point-three percent. I went from forty-one percent to forty-two-point-three."
"One-point-three percent improvement after a process that nearly caused a cascade failure in your channel architecture." Gao Jun's voice was the particular flat of a man revising his expectations downward. "The division's model predicted seven to nine percent improvement from this single optimization."
"The division's model didn't account for asymmetric translation in partial fragments."
"The division didn't have partial fragments to account for." He erased his dust diagram with his boot. Drew a new one: the crossing point, four pathways, the fragment now centered at the intersection with arrows showing directional flow. He marked the reverse-flow arrows with X's. "You need a full-capacity fragment at the bridge point. A partial can't handle bilateral translation. The capacity deficit creates directional bias. The fragment prioritizes the stronger signal source, which is the infrastructure-derived cluster, and under-services the weaker native cluster."
"I don't have a full-capacity fragment to spare."
"Then the bridge optimization requires a different approach." The stick tapped. Gao Jun was processing, not through his overlay, but through the older, slower mechanism of a human brain working a problem it hadn't seen before. The theoretical models were failing against practical reality. The analyst was being forced into engineering. Not studying the system, but fixing it. "What if the bridge isn't a fragment? What if it's a channel modification? Instead of placing a component at the crossing, you widen the crossing itself. Increase the junction's capacity so the energy flows don't need translation. They pass through a larger space that accommodates both architectural languages."
"Widen a channel junction."
"Your routing sense can modify channel architecture. You repositioned a fragment. That's a more complex operation than widening a pathway. The channel walls are formation-frequency boundaries. If you reduce the boundary intensity at the crossing point, the junction opens. Both signal types pass through without needing a translator."
The theory was elegant. The practice was another question. Lin Feng's routing sense examined the crossing point, the four pathways intersecting at fragment twenty-four's new position. The channel boundaries at the junction were formation-frequency walls, maintained by the template's structural integrity. Weakening those walls would widen the junction. It would also weaken the structural separation between the two clusters. The node architecture and the native architecture would bleed into each other at the junction. Mixing.
"If I widen the junction, the two architectures mix at the crossing point. The node data and my native template data start interfacing without separation."
"And?"
"And I don't know what happens when infrastructure-class formation architecture mixes with biological cultivation architecture without a mediating structure. The Devourer's Path integrates through consumption, a controlled process with buffering and filtering. Direct mixing at a widened junction is uncontrolled integration. Raw."
Gao Jun's stick paused mid-scratch. The analyst's face changed. Not alarm, but recognition. A researcher encountering the moment where theory meets a boundary that theory doesn't describe.
"The division's models don't cover that scenario."
"Good. Then we won't test it today."
"Agreed."
---
The afternoon brought visitors.
Lin Feng's routing sense detected them first: two formation signatures approaching from the east, following conduit lines through the crystal terrain. Human signatures. Conventional template architectures, forty to forty-five fragments each. Fourth-stage practitioners moving at a pace that suggested travel rather than pursuit but carried the directional intent of people who knew where they were going.
"Two practitioners. East. Forty-plus fragments each. Coming this way."
Gao Jun was at the fissure's surface; he'd climbed up to check sight lines and hadn't come back down. His voice carried from the rim, ten meters overhead, filtered by the crystal walls and the stone architecture.
"Bearing?"
"Direct. Following the elevated conduit line. The same line that led us here."
A pause. The silence of a man whose analytical overlay was scanning the same direction and confirming what Lin Feng's routing sense had already reported.
"Survey replacement team," Gao Jun said. His voice had changed. Not the analyst's measured tone. Something older. Harder. "The research division deployed a follow-up to the team that got hit by the third-generation organisms. The replacement team is using the conduit grid's energy patterns to navigate, standard division procedure. They're following the elevated line because elevated lines lead to infrastructure installations, and infrastructure installations are what the division studies."
"They'll find the hub."
"They'll find the fissure. The entrance mechanism is sealed. Your authorization opened the door but the door closed behind us. Without supervisor-class access, they can't get in. But they'll document the location, map the surface architecture, and report to the directorate." He climbed down the rope. Fast, the sixty-three fragments making the descent look effortless. His boots hit the stone platform with a thump that echoed through the corridor. "If they detect your routing signal—"
"I'm suppressing."
"You're suppressing at forty-two percent efficiency. Your signal leaks. The surges are less frequent since the transfer payload finished integrating, but the suppression gaps are still there. A competent formation sensor at forty-five fragments will detect you within five hundred meters."
The two signatures were three kilometers east. Moving west. Following the conduit line. Lin Feng tracked them through the crystal soil beneath the hub's stone floor, his routing sense conducting through the contaminated ground, the same technique he'd used from every granite shelter in the Barrens.
"How long until they reach the fissure?"
"At their pace? Two hours."
"Can we leave?"
"Through the fissure? They'd see us climbing out. The western approach from the fissure crosses open crystal terrain, no cover for six hundred meters." Gao Jun's hand was on his blade. The formation-treated steel caught the corridor's amber light. "We stay inside. Sealed door. They can't get in. They document the fissure, file their report, move on to the next survey point."
"And the report reaches the directorate."
"The report reaches the directorate. The directorate learns that Hub Seven-West's conduit line has elevated energy density. They deploy a research team. The research team brings better equipment. Better equipment detects the sealed entrance mechanism. The directorate gets interested." He sheathed the blade. Not combat. Patience. "We have maybe a week before the directorate's response reaches this location. The cascade isn't the only clock we're on anymore."
Lin Feng sat on the diagnostic platform. The four active pillars hummed their idle frequency. The station's passive monitoring continued, scanning his template, tracking the repositioned fragment twenty-four at its new crossing-point location, measuring the one-point-three-percent efficiency gain that had cost him a cramped right hand and two hours of work.
One-point-three percent. Seventeen optimization points. If each one yielded similar gains, and the research division's models couldn't predict whether they would, because the models were wrong about bilateral translation and might be wrong about other things, he could reach approximately sixty-four percent efficiency through manual optimization alone. Not the eighty percent the station promised. But sixty-four percent from a template that had been running at forty-one was a meaningful improvement.
If he had the time. If the research division didn't find him first. If the network's waking administrative protocols didn't reach operational status and start sending commands through the backdoor. If the Barrens' corrupted ecology didn't produce something worse than third-generation organisms in the next month.
If. A word that engineers hated. Engineers worked with specifications, tolerances, defined parameters. *If* was the domain of gamblers and generals and boys with dead arms sitting on diagnostic platforms in underground workshops, trying to debug a template architecture that nobody had ever used before by applying theoretical models that nobody had ever tested.
"Optimization point seven," Lin Feng said. "The diagnostic identified a routing loop in the native cluster. Energy circulating between fragments nine and fourteen without contributing to output. Wasted cycles."
Gao Jun picked up his stick. Drew the loop in the dust. Nine and fourteen, connected by a channel pathway that folded back on itself, the energy traveling in a circle that produced heat in his channels but no useful work. A short circuit. A bug in the wiring.
"Breaking the loop requires disconnecting the pathway between nine and fourteen. The energy currently in the loop will discharge when the circuit breaks. Where does it go?"
"I'll route it to the cornerstone. Fragment one can absorb the discharge."
"How much energy is in the loop?"
Lin Feng's routing sense measured. The loop had been cycling since the node consumption, seven days of accumulated energy, circulating at increasing intensity as the cascade raised the ambient formation levels and the loop drew power from the environment through the channels' passive absorption.
"More than I expected. Seven days of accumulation."
"Discharge it slowly. If the full load hits the cornerstone at once—"
"I know." He knew. The cornerstone was at eighty percent capacity. A sudden dump of seven days' worth of cycling energy could push it past its operational limit. The channel would blow. Not dramatically; formation channels didn't explode. They degraded. The frequency boundaries that defined the channel's structure would weaken, the capacity would drop, and the cornerstone that anchored his entire template would become a seventy-percent channel or a sixty-percent channel, and every fragment and pathway that depended on the cornerstone's output would degrade proportionally.
Slow discharge. Controlled. The engineering approach rather than the quick fix. He opened a bleed pathway from the loop to the cornerstone, a thin channel, restricted flow, the energy trickling from the short circuit to the cornerstone at a rate the eighty-percent channel could absorb without stress.
The loop began to drain. Fragment nine's output to fourteen decreased as the circulating energy bled off. The heat in the loop's channels, a warmth he'd been carrying for seven days without consciously noticing, diminished. His right shoulder relaxed. He hadn't realized it was tense. The loop had been producing a low-grade stress response in the muscles nearest its channel pathway, the chronic formation-frequency irritation of a short circuit running in his body like a machine vibrating against its housing.
Ten minutes. The loop drained. The short circuit broke as the energy level dropped below the threshold needed to sustain circulation. Fragments nine and fourteen disconnected their circular pathway and the energy that had been wasting in the loop redistributed through the template's normal channels.
The diagnostic station's passive monitoring registered the change. His efficiency climbed. Forty-two-point-three to forty-four-point-one. Nearly two percent from breaking a single loop. More than the bridge fragment had gained.
"Better," Gao Jun said. He was reading the station's output through his overlay. "Point-one-seven improvement over the bridge optimization. The loop was costing you more than the junction inefficiency." His voice carried the recalculation of a man whose models had predicted a smaller gain and was adjusting his framework to account for the discrepancy. "The division's theoretical models underestimate the cost of routing loops. The models assume loops are passive, circulating energy without affecting the template. The actual cost includes the thermal stress on adjacent channels, the compensatory routing that other fragments perform to work around the loop's disruption, and the ambient energy absorption that feeds the loop from the environment."
"The models are wrong."
"The models are incomplete. The models are built from external observation and structural analysis. They can't account for internal states: the thermal effects, the stress responses, the secondary compensation patterns. Those are phenomena that only exist inside a functioning template. Inside your template." He looked at his dust diagram. The loop, erased. The efficiency gain, noted in scratched numbers beside the crossing-point calculation. "The division spent three centuries building models. You've invalidated two of them in an afternoon."
"Good."
Gao Jun's mouth twitched. The analyst's version of amusement, recognizing the absurdity of three hundred years of academic work meeting a single practical test and bending.
"Optimization point twelve," he said, and drew a new diagram.
---
They worked through five more optimization points before Lin Feng's channels refused to cooperate. The fifth manual adjustment, a fragment reposition similar to the twenty-four bridge but targeting a different junction in the native cluster, produced spasms in his left leg that lasted eleven minutes and convinced both of them that the template needed rest between modifications. The biological substrate that carried the formation architecture was not infinitely tolerant of restructuring. His body needed time to adapt to each change before the next one was attempted.
Final efficiency: forty-seven-point-two percent. Six-point-two percent improvement from manual optimization. Five adjustments completed, twelve remaining. His right hand still cramped intermittently. His left leg tingled. His right shoulder was relaxed for the first time in a week, the loop-elimination having removed a chronic stress source he'd normalized into background noise.
The two survey team practitioners reached the fissure at late afternoon. Lin Feng tracked them from the workshop, routing sense through the stone floor, through the crystal substrate beneath the hub's architecture, reading their formation signatures as they circled the fissure's perimeter. They spent forty minutes mapping the surface. Their templates produced analytical pulses that his upgraded perception identified as survey equipment, the same kind of formation-frequency measurement tools that Gao Jun's analytical overlay used, less sophisticated but functionally similar.
They didn't detect him. The hub's stone architecture dampened his signal. The sealed entrance blocked the survey pulses from reaching the interior. The two practitioners documented a fissure in the crystal surface with pre-Abandonment stone architecture visible in the walls, filed their observations through a conduit-network communication that Lin Feng intercepted and read through his data-layer perception, and moved on.
Their report was brief. Professional. The kind of data packet that a field team sends to headquarters without editorial commentary.
*Survey Point W-7. Fissure formation, 40m x 5m. Pre-Abandonment architecture confirmed. Sealing mechanism detected (north wall, subsurface). Authorization class: undetermined. Elevated conduit energy consistent with cascade propagation. Recommend priority investigation. No hostile organisms encountered. Proceeding to Survey Point W-8.*
Priority investigation. Recommend. The words that would bring the research division's attention to Hub Seven-West. Not immediately, not tomorrow, but soon. A week, Gao Jun had estimated. Maybe less, given the cascade's significance and the loss of the previous survey team to third-generation organisms. The directorate would be aggressive. They'd lost people. They'd want results to justify the cost.
Lin Feng lay on the workshop floor. The stone was cold. The amber light was steady. The diagnostic platform hummed beside him, the station at idle, the passive monitoring tracking a template that was six percent more efficient than it had been that morning and still fifty-three percent short of its theoretical maximum.
Forty-seven percent. Twelve optimization points remaining. The station promising eighty percent when the power reached sixty. The backdoor pulsing its twelve-minute status report to a network that was getting closer to operational with every hour of cascade energy.
"I need to work faster," he said to the empty chamber.
The chamber didn't answer. The hub's dormant architecture hummed at the edge of perception. Outside, the Barrens cooled into their nightly silence, and the conduit grid carried data that nobody had read for ten thousand years, and somewhere east, a survey report traveled through the network toward people who would come looking for what they'd found.
Gao Jun was already climbing the rope. Heading for the surface. Another supply run to the western settlements, eight kilometers of normal terrain, a world that existed beyond the crystal ground and the formation infrastructure and the engineering puzzles that were rewriting Lin Feng's body from the inside.
"I'll be back by midnight," the analyst called down. The voice echoed off crystal walls. "Don't optimize anything while I'm gone. Your channels need eight hours minimum between adjustments."
The rope creaked. Boots on crystal. Then quiet.
Lin Feng closed his eyes. His routing sense extended through the hub's floor, through the conduit network, reading the data-layer traffic that flowed through the western Barrens' infrastructure like whispers through plumbing. Status reports. Diagnostic pulses. The automated chatter of a network rebooting itself, component by component, node by node.
And in the chatter, something new. A message that hadn't been in the data stream an hour ago. A message that his consumed node architecture flagged before his conscious mind registered it, the infrastructure protocols in his template recognizing the message format and producing an alert that bypassed his normal perception and hit his awareness like a tap on the shoulder from inside his own skull.
*Network Administrative Protocol: Component Registration Query. All active nodes report current operational status and location. Compliance mandatory. Response window: 72 hours.*
The network was requesting a roll call.
And his template, the consumed junction node embedded in his channels, the infrastructure component that was still registered as part of the network, was already composing a response.
